[Renal tubular damage after rapid intravenous contrast study with iopamidol]

Reference is made to results obtained in 53 nephropathics in the study of urinary elimination of alphaglycosidase and lysozyme before and after rapid contrastography with sodium and meglumine diatrizoate and with iopamidol. A statistically significant difference in alphaglycosidase was evident with both media, whereas no change was noted for lysozyme. As far as the evaluation of alphaglycosidase was concerned, the tubular alteration induced by each medium was the same in terms of statistical comparison of the mean differences before and after urography.
